Types of Muscle Contractions Chapter 7
Tonic Contraction • Continuous, low-strength muscle contraction • Posture
Twitch Contraction • quick, jerky response to a stimulus
Tetanic Contraction • a sustained contraction or “tetanus” • many twitches put together
Concentric Contraction • Type of isotonic contraction • Movement at a joint • Shortening of a muscle • Insertion end moves toward the position of origin
Eccentric Contraction • Type of isotonic contraction • Lengthening of a muscle • Insertion moves away from the origin
Isometric Contraction • Increased tension with no movement • The muscle tension increases but the muscle does not shorten
